===========================================================

Explanation:

The general cosine template is

y = A*cos(B(t - C)) + D

where in this case

We only really need to worry about the B value. To get the period T, we do the following

T = 2pi/B

T = (2pi)/(pi/4)

T = 2pi * (4/pi)

T = 8

Note how the pi terms canceled. The period is 8 seconds, which is the length of one full cycle. This is the time it takes for the pendulum to do one full swing (eg: start at the right, swing to the left all the way, then swing back to the right again).

The result of 8 we got has nothing to do with the D = 8 value (this D value could be any other number and T = 8 would still be the case as long as B doesn't change of course).

Answer:

First, find the cost function of DoItRight Housekeeping:

The y-intercept(b), representing the initial cost, can be calculated by substituting in values to the function:

[tex]f(x)=12x+b\\26=12(1.5)+b\\b=26-18=8[/tex]

Therefore, the function for two companies are:

When comparing the two functions, it's shown how CleanIt has a greater y-intercept than DoltRight, meaning that CleanIt has a greater initial cost than DotRight. The y-intercept is when the graph intercepts the y-axis, therefore, the coordinates there would be (0, y-value), which, in this case for CleanIt company, will be (0, 16). While CleanIt has a greater y-intercept(initial cost), DoItRight has a greater slope, meaning they cost more per hour.

Answer:

D. The graph of G(x) is the graph of F(x) flipped over the y-axis and

stretched vertically.

Step-by-step explanation:

since there is a negative, there must be a reflection. the reflection is over the y-axis because it is outside the x-value (-F(x) not F(-x))

the same goes for the vertical stretch. we know it is a vertical stretch because the 3 is outside the x-value (3F(x) not F(3x))

The area (A) of the sector is calculated as

A = area of circle × fraction of circle

   = π × 4² × [tex]\frac{17}{24}[/tex]

   = 16π × [tex]\frac{17}{24}[/tex]

   = [tex]\frac{16\pi (17)}{24}[/tex]

Answer:

f(7) = 16

Step-by-step explanation:

f(7)  

Let x = 7

We use the first part of the function since 7 > 4

3(7) -5

21 -5

16

f(7) = 16

Step-by-step explanation:

AC = 20

AB = 18

BC² = 20²+ 18² -2•20•18•cos(52°)

BC² = 280.72

BC = √280.72

BC ≈ 16.75

Angle C:

18² = 20² + 16.75² -2•20•16.75•cos(C)

324 = 400 + 280.72 -670•cos(C)

cos(C) = -356.72/-670

cos(C) ≈ 0.53

acos(0.53) = C

C = 57.8°

Angle B:

180-52-57.8 = 70.2°

Answer:  (2, 1)

======================================================

Explanation:

Let's add the equations straight down

After those three things happen, we're left with 3x = 6 which solves to x = 2 after dividing both sides by 3.

Now let's use this x value to find y

2x-y = 3

2(2)-y = 3

4-y = 3

-y = 3-4

-y = -1

y = 1

Or we could use the other equation

x+y = 3

2+y = 3

y = 3-2

y = 1

which gets us there in fewer steps.

So that's how we get to the final answer of (x,y) = (2,1)

Explanation:

I'll assume that both lots are not adjacent. So we have two separate rectangles that aren't touching.

We use the rectangle perimeter formula

P = 2(L+W)

where L is the length and W is the width. For the first rectangle, we have L = 45 and W = 22, so

P = 2(L+W)

P = 2(45+22)

P = 2(67)

P = 134

You need 134 feet of fencing for the 45 ft by 22 ft rectangle.

Repeat for the other rectangle

P = 2(L+W)

P = 2(24+16)

P = 2(40)

P = 80

You need 80 feet of fencing for the 24 ft by 16 ft rectangular lot.

Overall, you need 134+80 = 214 feet of fencing

------------------------

Extra info (optional section):

Now if the two lots are touching in some way, then you won't need as much fencing. This is because the two lots will share the bit of fencing between them. This might apply to a portion of one side, or the entire side, of either rectangle. It depends how the lots are laid out.

The assumption that the lots aren't adjacent considers the worst case scenario, aka the situation where you'll need the most fencing (hence the largest cost). This will allow you to prepare for the worst and not be caught off guard. All of this assumes there is no waste, and that there are no gaps or overlaps. If there is expected to be some inefficiency of waste (which is fairly realistic in my opinion) then it's probably a good idea to slightly overshoot this target.

Hi there!

According to the question;

The sum of two number is 59. And the Smaller number is less than the bigger one by 7,

Let the bigger number be "X" then smaller number will be x-7.

Then;

x + (x-7) = 59

2x = 59+7

X = 66/2

Therefore, the bigger number (X) is 33 and smaller number (x-7) is 26.

James should define that the rays must be collinear. the two rays coming from the same point will form collinear rays which will form an angle at end point.

Answers and step-by-step explanation:

First, we add up all the totals for the box tops. This would be 3,750+2,301+1855 which totals to 7,906. Then, we take each individual box top value and divide it by 7,906 to get the fractions. For Mr. Aceves' class, the percentage is 47%, for Mrs. Baca's class, the percentage is 29% and finally for Mr. Canyon's class, the percentage is roughly 24%. This would mean that Mr. Aceves' class should get $282, Mrs. Baca's class should get roughly $174, and Mr. Canyon's class should receive $144.

Step-by-step explanation:

8x³ - 27y³ ← is a difference of cubes and factors in general as

a³ - b³ = (a - b)(a² + ab + b²)

8x³ - 27y³

= (2x)³ - (3y)³

= (2x - 3y)((2x)² + 2x(3y) + (3y)²) , that is

= (2x - 3y)(4x² + 6xy + 9y²)

B did it on edg

Step-by-step explanation:

The expression that shows how Joshua could use place value to break up this problem and solve it is:

(30 + 8) x (10 + 2)

Option B is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

38 x 12

This can be written in place value as,

38 = 3 tens and 8 ones

12 = 1 tens and 2 ones

So,

38 = 30 + 8

12 = 10 + 2

Thus,

The expression used is (30 + 8) x (10 + 2)

Step-by-step explanation:

60 étudiants dans un foyer ont assez de nourriture pour 30 jours. Si 20 étudiants supplémentaires rejoignent l'auberge après 10 jours, combien de temps durera la nourriture restante ?

Let say A the quantity of food

60 students in a hostel have food enough for 30 days ==> A=k*60*30

The Measurement of the second triangle would be 4.5, 6, 7.5. and the dilation type is reduction.

Step-by-step explanation: The sizes you have will be multiplied by the dilation factor 0.75.

6*0.75=4.5, 8*0.75=6, 10*0.75=7.5.

Have a good day.

The dilated form of the sides of the triangle is 4.5,6, and 7.5.

Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased. The scale factor is defined as the proportion of the new image's size to that of the previous image. decision-making.

Given that a triangle has sides measuring 6, 8, and 10 cm. Using a dilation factor of 0.75.

The measurement of the second triangle would be 4.5, 6, and 7.5. and the dilation type is reduction.

The sizes you have will be multiplied by the dilation factor of 0.75.

6 x 0.75=4.5,

8 x 0.75=6,

10 x 0.75=7.5.

Therefore, the dilated form of the sides of the triangle is 4.5,6, and 7.5.
